    (1)钛白粉:又称二氧化钛,是用于油墨、涂料、塑料的主要白色品种。

    (2)氧化锌:氧化锌又称锌白、锌氧粉,分子式为ZnO,熔点1720℃,折射率1.92-2.00。氧化锌常用于橡胶着色,也用于塑料着色,如ABS、聚苯乙烯。

    (3)锌钡白:锌钡白又称立德粉,是硫化锌与硫酸钡的混合物,组成分子式可写成ZnS+BaSO4。其中硫化锌含量有15、30、40、50等几种。锌钡白可配制出良好白色,其遮盖力也比较强,介于氧化锌和二氧化钛之间。但由于性能优越的二氧化钛在塑料着色中广泛应用,锌钡白应用受到很大限制。

    Decoration must see: several commonly used white pigment

    (1) titanium dioxide: also known as titanium dioxide, is used in inks, coatings, plastics, the main white varieties.

    Zinc Oxide: Zinc Oxide (2) also known as zinc, zinc oxide, molecular formula ZnO, the melting point of 1720 DEG C, the refractive index of 1.92-2.00. Zinc Oxide is commonly used in rubber coloring, but also for plastic coloring, such as ABS, polystyrene.

    (3): also known as lithopone lithopone lithopone, is a mixture of zinc sulfide and barium sulfate, which molecular formula can be written as ZnS+BaSO4. The content of zinc sulfide is 15, 30, 40, 50 and so on. Barium zinc white can be used to make a good white, its coverage is relatively strong, between Zinc Oxide and titanium dioxide. But because of the superior performance of titanium dioxide is widely used in plastic colouring, lithopone application is very limited.
